Network Traffic Project Work Log

Currently I am working on a project to collect port traffic data from a few network devices. These are the interesting areas of that project

.env file to store credentials.
Read port data from a csv file and store in a list.
SSH to the devices and collect traffic data from devices using netmiko library in Python.
Resolving errors that occur during traffic collection.
Usage of else in exception handling.
Implement a retry mechanism to run when traffic fetching fails.
Extract the data from netmiko result using regular expressions and store in Python data structures. Used regex capture groups for extracting the required data.
Convert traffic utilisation to traffic rate by using port type.
Calculate total traffic of ports.
Write results to csv files.
import a function from a parent directory.
In version 2.0 rewrote the project to use Python classes.
Writing utility functions in a file named util.py

Functionalities that planned to be implemented

add tabulate for printing output on commandline
add option parsing using argparser.
database implementation
cache implementation
charting

Retrying Iteration of a Loop if it gets failed

In this post I am going to explain a code block which I used for retrying iteration of a loop if it gets failed.

This is the code

    port_traffic_data_list = []
    # variables for adding total traffic
    total_in_traffic = 0
    total_out_traffic = 0
    for port in port_list:
        retries = 0
        max_retries = 5 …
